PLOW-COLTER.

SPECIFIGATION`formi11g part of Letters Patent o. 263,079, dated August 22, 1882. Application tiled May 10, 1882. (No model.)

To all 'whom zt 'may concern:

Be it known that I, Gon/[Ea C. VINCENT, a citizen of the United States, residing at Greensborough, in the county of Green and State of Georgia, have invented certain new and useful Improvements in Plow-Oolters, of which the following is a speciiication.

My invention relates to improvements in the class of colters that are secured to and rest against the plow-shovel to facilitate its operation; and the objects of myimprovements are, first, to provide a colter with an arm substanrially at right angles with the back ofthe blade and adapted to secure the plow or shovel to the standard without any additional fastenings; and, second, to provide a rigidand substantial connection between the colter and the plow-standard. I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure l is a perspective view of the colter connected to a shovel-plow and its standard, thclatter being shownin dotted lines. Fig. 2 is a perspective view of the colter detached. Fig. 3 is a vertical section through a plowshovel, with the colter secured thereto. Y

Heretofore colters ot' this class have been secured either to the shovel or to its standard, or to both together, by means of independent bolts passing through lugs or lianges forming part of said colters; but they have not the strength and rigidity thatl obtain by my construction.

In the accompanying drawings, A represents the colter-blade, which tapers in two directions, being much broader at its top than at its point a, and havinga broad back, a', opposite its cutting-edge, and from this back there projects, at an angle ot ninety degrees thereto, an arm, a2, made integral with the blade and adjoining its upper end. The portion of this arm adjacent to the back of the blade is preferably rectangular in form to produce a fitting connection with the rectangular opening bin the upper end of the shovel B, and also with the standard G. The outer end of the arm a2 is cylindrical and screw-tapped to engage with the retaining-nut D, adapted to abut against the rear portion of the standard. From the back ofthe blade A, about two-thirds down (more or less) from the top, there projects a pin, a3, to enter a perforation, b3, in the shovel and retain the two together at that point, and this pin may extend beyond the rear of the shoveland enter the standard, steadying the three parts together at that point. In addition to the arm a2 and steadypin a3, uniting the colter and shovel together, it is desirable that a small groove or indentation, b2, should be made in the center or crown line of the shovel to receive the point a. of the colter to prevent the tine roots, grass, or weeds from entering and lodging between the colter and shovel.

The shovel shown in the drawings to illustrate the application of the colter is one ofthe narrow kind; but it is evident that its width and shape may vary.

The standard shown b v dotted] lines is more especially intended to representa wooden or solid-metal standard; but the coller may as conveniently be secured to a forked metallic standard by placing a broad washer between the nut D and the back ofthe branches of this class ot' standards.

Having now fully described my invention, I claim- The combination, with a plow-standard and a shovel provided with perforations b and b3, of a colter-blade having integral therewith the screw-tapped arm a2, and the steady-pin a3, projecting from the back of the blade, substantially as and for the purpose described.
